DC LC Low-pass filter EMI electromagnetic interference EMC car audio high-frequency filter switching power supply ripple filter
This circuit is composed of three-stage filtering, the first stage LC filter circuit, the second part is common-mode EMI filter. The third part is the secondary LC filter circuit
LC filter is generally called passive filter. It is a traditional DC power supply noise compensation device composed of inductors and capacitors. Purify the DC power supply and common-mode filter can suppress the problem of fast state group pulses with repetition frequency of several kilohertz on the site of a certain art user.
Input : DC Output : DC Voltage : 50V (higher voltage can replace the electrolytic capasitor to improve)
This module is suitable for eliminating the use of DC power supply with electromagnetic interference. It can be applied to filter after power on, automobiles, motorcycles, and DC with stroger electromagnetic interference than caiibration.
